How would the values of $\mathrm{v}_{\mathrm{p}}$ for carbon dioxide gas compare to that of nitrogen gas at a given temperature? (Hint: Carbon dioxide gas has a molar mass of $44 \mathrm{~g} / \mathrm{mole}$; nitrogen has a molar mass of $28 \mathrm{~g} / \mathrm{mole}$.)
A) $v_{p}$ will be larger for carbon dioxide.
B) $v_{p}$ will be larger for nitrogen.
C) $v_{p}$ will be equal in both cases.
D) One does not have enough information to tell for sure.

Question

Quizplus · Accepted Answer

The speed of sound ($v_p$) in a gas is inversely related to the square root of the molar mass of the gas. Since nitrogen has a lower molar mass than carbon dioxide, the speed of sound will be higher in nitrogen.
